Title: Improvements in and relating to systems of ship propulsion
IPC: B63H23/24
Filed: 1925-10-26
Abstract: 263,261. British Thomson-Houston Co., Ltd., Clough, F. H., and Pollock, A. A. Oct. 26, 1925. Dynamos and motors combined for transmitting power.-A system of electric propulsion for ships wherein one or more prime movers are connected in series with a plurality of propeller motors each having independent field control is provided with means whereby the excitation current of the generators is increased proportionately with the motor field current. The four generators have their armatures 1 connected in - series with the armatures 2 of the two propeller motors. The generator field 3 and motor fields 4 are excited proportionately by an exciter 5, the fields 3 being in series with rheostats 6 controlling the fields 4. In an alternative arrangement, the motor field current excites a booster having its armature connected in the circuit of the generator fields. Specifications 210,524 and 226,960 are referred to.

Title: Improvements in or relating to sliding clasp fasteners
Inventor: EVANS HERBERT
IPC: A44B19/14
Filed: 1957-09-20
Abstract: 868,414. Sliding clasp fasteners. FLEX FASTENERS Ltd. Aug. 26, 1958 [Sept. 20, 1957], No. 26788/58. Divided out of 868,413. Class 44. A method for use in the manufacture of sliding clasp fasteners, comprises the steps of providing a tube 1 of nylon or other plastic material, the tube being split lengthwise, pressing at least a portion of the tube substantially flat, and while flat, punching or cutting out or otherwise removing portions of the tube walls so that after release of the pressure, split rings 7 remain which are provided with coupling elements 8, and are connected by bridge pieces 9 to form a string of connected interlocking members. The string may be fixed to a carrier tape 11 by sewing or gluing the edge thereof into the split or the string may be woven in to the tape by weft threads while the weaving of the tape proceeds. The tube may be flattened by opening the same at the split 2 so that edges 3 and 4 are remote from each other, or the tube may be pressed so that the edges 3 and 4 lie adjacent each other and the material of the tube forms two superimposed layers, Figs. 7 and 8 (not shown). In another arrangement, Fig. 9 (not shown), a twin tube is employed which is split at each side remote from a common centre portion. The tube is flattened and cut to produce cut-outs on each side of the centre part and the tube subsequently cut longitudinally through the centre part to produce two strings, each similar to that shown. The coupling elements of one string may. be displaced longitudinally in relation to the coupling elements of the other string. In an alternative arrangement Figs. 15-18 (not shown) the twin tube is split at the common centre portion and the coupling elements formed at the outer portions remote therefrom, the tube subsequently being cut longitudinally to produce two strings each similar to that shown. In the arrangement according to Fig. 19, a split tube is substantially flattened against a die 61 and cut-outs 66 are produced by a punch 62. In an arrangement according to Fig. 20, (not shown) the string is passed through openings in a ladder-like tape which is then bent about the bridge pieces of the string and the overlying parts of the tape secured by stitching or gluing. According to Figs. 21 and 22 (not shown) the string is secured to a tape between two branches at the edge of the tape and in which a third branch engages the split, respectively.

Title: Improvements in or relating to wireless transmission or receiving apparatus
IPC: H04B14/00
Filed: 1937-10-04
Abstract: 505,079. Multiplex wireless signalling; television. BLUMLEIN, A. D. Oct. 4, 1937, No. 26796. [Classes 40 (iii) and 40 (v)] Two modulated carriers of the same wavelength but polarized in planes substantially mutually perpendicular are transmitted so that a receiver can selectively receive either or both of the transmissions by suitably disposed aerials e.g. dipole aerials. The two transmissions may be modulated with the same or different signals and may be radiated from adjacent or remotely situated transmitters. The transmissions may comprise television signals derived from the same picture through different colour filters and operate complementary receivers with screens arranged to fluoresce in the appropriate colours, which may be disposed at right angles to each other, the images being superposed by a half silvered viewing mirror. Alternatively or in addition the two carriers may be used for stereoscopic transmission of two aspects of a scene. In another embodiment the modulating signals are derived from two microphones to permit binaural reproduction of sound at the receiver. Reference has been directed by the Comptroller to Specifications, 331,667, [Class 40 (v)], 389,142, and 397,620.

Abstract: 535,298. Artificial filaments &c. DREYFUS, H., TAYLOR, W. I., and HILL, F. B. Oct. 3, 1939, No. 27094. [Class 2 (ii)] Filaments, yarns, and similar materials made of an organic derivative of cellulose and of an extensibility of at least 30 per cent. are wetted with water at a temperature below 60‹ C. and are subjected while wet to a stretching operation. The treated materials have an increased tenacity and still have an extensibility satisfactory for weaving, knitting, and other operations. The materials may have initially an extensibility of 35-40 per cent. or more. Materials of cellulose acetate or other ester or of ethyl cellulose or other cellulose ether may be treated. The materials may be obtained by dry spinning while maintaining the spinning solution at a high temperature. The solution, in the case of cellulose acetate in acetone, may be heated to 65-70 or even 80‹ C. The temperature of the solution should be above the boiling point at atmospheric pressure of the solvent medium and the temperature of the evaporative medium is preferably also above the boiling point of the solvent medium. Stretching may be effected by passing. the materials, after wetting them with water, between positively driven rollers. The materials may be stretched to the extent of 25-35 per cent. The Provisional Specification describes also the stretching of the filaments or similar materials during their passage through steam or hot water at temperatures of the order of 110‹-135‹ C.
